3^8=6561. The math is off on that one. Also, these are all decent enough to do with just mental math… except the one with multiple factorials to be added together. That one doesn’t really fit the style of the quiz and is just a real pain to do mentally.

If you want to say 5 squared, to have it appear as 52 just type 5 < sup > 2 < / sup> , removing all the spaces in that expression.
